[] Articles [ ] [Designing perturbative metamaterials from discrete models pp323 - 328]( doi:10.1038/s41563-017-0003-3 A perturbative method is proposed for the systematic design of mechanical metamaterials, where each element of the discrete model is associated with individual geometric features of the metamaterial, through the weak interaction between the unit cells. [ ] [Universal strategy for Ohmic hole injection into organic semiconductors with high ionization energies pp329 - 334]( Naresh B. Kotadiya, Hao Lu, Anirban Mondal, Yutaka Ie, Denis Andrienko et al. doi:10.1038/s41563-018-0022-8 It is shown that Ohmic contacts for the injection of hole carriers into organic semiconductors with high ionization energy can be formed by adding ultrathin interlayers with higher ionization energy. [ ] [SiGe epitaxial memory for neuromorphic computing with reproducible high performance based on engineered dislocations pp335 - 340]( Shinhyun Choi, Scott H. Tan, Zefan Li, Yunjo Kim, Chanyeol Choi et al. doi:10.1038/s41563-017-0001-5 Controlled widening of threading dislocations in SiGe layers epitaxially grown on Si allows the realization of resistive switching devices with enhanced uniformity, high on/off ratio and long retention times. [ ] [A molecular cross-linking approach for hybrid metal oxides pp341 - 348]( Dahee Jung, Liban M. A. Saleh, Zachariah J. Berkson, Maher F. El-Kady, Jee Youn Hwang et al. doi:10.1038/s41563-018-0021-9 TiO2 and other metal oxides were interfaced with molecular boron clusters to form a hybrid material. This modifies the electrochemical and photocatalytic properties, enabling fast electron transfer and dye degradation under red light.
